Abstract： Objective　To analyze the epidemic situation and risk factors of schistosomiasis in Hubei Province from 2015 to 2022, and to provide a scientific basis for the goal of all schistosomiasis-endemic counties in the province reaching the elimination standard by 2030. Methods　According to the requirements of the National Schistosomiasis Surveillance Plan (2014 edition) and National Schistosomiasis Surveillance Plan (2020 edition), the snail situation and the risk of wild fecal transmission, along with regional distribution in schistosomiasis endemic areas in Hubei Province from 2015 to 2022 were analyzed and the risk was rated. Results　From 2015 to 2022, a total of 60 203 risk monitoring environments per time was carried out, with 10 223 460 frames of snails inspected, capturing 2 344 094 snails, among which 1 357 479 live snails, and an average density ranging from 0.07-0.29 snails/0.11 m2. In 2015 and 2017, 11 and 3 schistosomiasis-infected snails were detected respectively, corresponding to 3 and 2 positive snail environments. The proportion of wild feces distribution environment in the total monitoring environment showed a downward trend, with cow dung accounting for the highest proportion (69.27%). A total of 19 549 wild feces were collected, of which 78 were positive for schistosomiasis. Since 2018, only one positive cow dung was found in 2019, and none in other years. From 2015 to 2020, the density of live snails and the proportion of wild feces in the monitoring environment in each risk monitoring county (city, district) had significantly reduced, with areas of higher snail density such as Gongan County, Yangxin County with higher density of live snails decreasing to below 1 per 0.11 m2 from 2017. Among the 60 203 risk monitoring environments, 53 were identified as GradeⅠrisk (not detected since 2020), 1 999 as GradeⅡrisk, and 58 030 as GradeⅢrisk. Conclusions　From 2015 to 2022, the overall schistosomiasis epidemic in Hubei Province showed a downward trend. However, the risk of schistosomiasis transmission still exists in some areas. In the future, we should continue to strengthen the epidemic monitoring in key areas, improve the sensitivity and level of monitoring, and prevent the rebound of the epidemic.

Objective To assess the relationship between gastric carcinoma perfusion imaging parameters with the multislice spi-ral CT (MSCT)and the tumor angiogenesis(MVD,VEGF).Methods (1)33 patients with gastric cancer were carried on perfusion CT scanning in the suspected lesions,and compared with operation and histological result.MSCT perfusion parameters tumor,such as local blood flow (BF),blood volume (BV),mean transit time of contrast agent (MTT),permeability surface (PS),were recor-ded,and compared with clinical pathological data.(2)27 patients of 33 cases which CT perfusion plane matching with operation pa-thology specimens performed with tumor microvessel density (MVD),vascular endothelial growth factor (VEGF)monoclonal anti-body immunohistochemical examination of MVD,the most intensive areas of high power (×200 HP)field counted,and VEGF stai-ning positive judged.Results Achievement ratio of gastric carcinoma MSCT perfusion imaging was 84.85% (28/33).The average value of BF,BV,MTT and PS were 63.658 ± 18.305,7.5 1 1 ± 2.427,1 1.952 ± 4.325 and 31.81 7 ± 13.533,respectively,and MVD was 37.7 ± 11.1/200 HP (range:13-60).VEGF was positive in 16 cases,negative in 11 cases.Gastric carcinoma undifferentiated group perfusion parameter PS value (35.1 5 ± 12.74 )and MVD (40.53 ± 10.66 )were higher than the differentiation group (23.90 ± 12.71 and 31.13 ± 9.82 )(P < 0.05 ),but BF,BV,MTT not statistically significant;Differences of CT perfusion parameters and MVD were not significant statistically between invasive serosa and noninvasive ;PS value (36.65± 12.80)of lymph node metastasis was greater than without metastasis(22.70 ± 1 1.1 5 )(P <0.01 ),the other was no significant difference;TNM staging Ⅲ,Ⅳ phase group of BF value (69.56 ± 1 6.49),PS value (34.90 ± 12.80)and MVD value (40.74 ± 10.53)were higher than Ⅰ,Ⅱ Group (49.63 ± 1 5.04),(24.50 ± 13.13)and (30.63 ± 9.61)(P <0.01).Spearman correla-tion analysis in confidence (two tails)of 0.01 was statistically significant between MVD in tumor tissues and gastric cancer MSCT perfusion parameters of BF (r=0.404)and MTT (r=0.371),whereas BV and PS were no significance.The regression equation of MVD with BF and MTT:MVD =1 6.602+0.1 50XBF +0.967XMTT,model checking of F values was 6.62,P =0.003.Conclusion The gastric carcinoma multi-slice CT perfusion imaging parameters BF,MTT and MVD,VEGF(+)was positive correlation, MSCT perfusion imaging parameters reflects tumor VEGF positive expression of gastric carcinoma.

Objective To compare the effect of fluoroscopic triggering method and empirical delay method on image quality in the liver Gd-EOB-DTPA dynamic enhanced MRI,and to investigate the value of fluoroscopic triggering method in Gd-EOB-DTPA dynamic enhanced MRI.Methods The patients underwent Gd-EOB-DTPA dynamic enhanced MRI were randomly divided into two groups according to the starting modes in the artery phase.Group A used fluoroscopic triggering method and group B used empirical delay method.Eliminating the images with severe respiratory motion artifacts,the quality of the remaining images in 78 cases of group A and 85 cases of group B were assessed in scores (excellent=5 scores;good=4 scores).Data was statistically analyzed with Mann-whitney tests,and P<0.05 was considered statistically significant.Results The excellent rate of the images in group A was 96.15% (75/78).The excellent rate of the images in group B was 67.06% (57/85).There were significant differences between the two groups in the excellent rate (χ2=27.889, P<0.001)and the image quality scores (Z=-4.747,P<0.001).Conclusion For the liver Gd-EOB-DTPA dynamic enhanced MRI, fluoroscopic triggering method is more likely to get better image quality and higher success rate in artery phase than empirical delay method,which indicates that fluoroscopic triggering method have obviously advantages in clinical applications.

Objective To study the endemic trend of schistosomiasis japonica in Hubei Province,so as to provide the theo?retical basis for surveillance and forecasting of schistosomiasis. Methods The time?series auto regression integrated moving av?erage(ARIMA)model was applied to fit the infection rate of residents of Hubei Province from 1987 to 2013,and to predict the shot?term trend of infection rate. Results The actual values of infection rate of residents were all in the 95%confidence inter?nals of value predicted by the ARIMA model. The prediction showed that the infection rate of residents of Hubei Province would continue to decrease slowly. Conclusion The time?series ARIMA model has good prediction accuracy,and could be used for the short?term forecasting of schistosomiasis.

Objective To understand the change of hydrological regime in the Yangtze River and schistosomiasis endemic situation after the implementation of Three Gorges Project in Hubei Province. Methods The data of hydrological regime of the Yangtze River,schistosomiasis epidemic situation,and Oncomelania hupensis snail status were collected and analyzed in Hu-bei Province from 2002 to 2012. Results After the implementation of the Three Gorges Project in 2003,the water level of the Yangtze River slightly rose from January to March,the average water level in May and August both reduced compared with that in 2002,and the time of water withdrawal was moved up. The endemic situation of schistosomiasis showed a decline tendency in areas along the Yangtze River in Hubei Province. The positive rate of serological tests in the residents and the Schistosoma ja-ponicum infection rate in bovine decreased by 2.97%and 92.64%respectively. The numbers of human and bovine infected with S. japonicum decreased by 48.35%and 94.48%,respectively. Conclusion After the implementation of the Three Gorges Proj-ect,the schistosomiasis endemic situation shows a decline tendency in the areas along the Yangtze River in Hubei Province ,but the long-term monitoring still need to be carried out.

Objective To understand the dynamic schistosomiasis situation in Hubei Province so as to provide the evidence for formulating the effective control strategy. Methods According to the Scheme of Schistosomiasis Surveillance in Hubei Province the 2009 edition 207 endemic villages were selected and investigated for the schistosome infections of residents and livestock and the distribution of Oncomelania hupensis snails. Results The average infection rates of residents and cattle were 0.35% and 0.15% respectively and the endemic situation of fishermen and farmers were relatively serious 0.44% and 0.42% respectively . The density of living snails was 0.30 snail/0.1m2 but no infected snails were found. Conclusion The en-demic situation of schistosomiasis in Hubei Province was stable in 2013 but the efforts for the infectious source control still should be strengthened.

Objective To analyze the change of schistosomiasis endemic situation in Hubei Province, 2008. Methods The data of schistosomiasis control in the whole province, surveillance sites and standard examinations were collected and analyzed. Results Among all the 63 endemic counties (cities, districts), 21 reached the criteria of transmission interruption, 19 reached the criteria of transmission control, and 23 reached the criteria of infection control in 2008. Villages of Category Three, Category Four and Category Five accounted for 52.10% , 27.80% and 20.09% of all the endemic villages in the whole province, respectively. The infection rates of population and cattle were 1. 70% and 2. 20% , which decreased by 27. 04% and 34. 33% when comparing to those in 2007. The snail area was 77 363 hm~2, with a reduction of 315.70 hm~2 comparing to 2007. In the 74 provincial surveillance sites, the infection rate of population and cattle were 1. 32% and 1. 85% , respectively, with reduction rates of 32.99% and 68.38% comparing to 2007. The snail area was 2 833.98 hm~2 and the area with infected snails was 215.35 hm~2, the densities of living and infected snails were 0. 37 snails/0.1 m~2 and 0.000 3 snails/0. 1 m~2, respectively, and the infection rate of snails was 0.08%. Comparing to 2007, the snail area, densities of living and infected snails and the infection rate of snails decreased by 3.81 % , 21.28% , 40.00% and 27. 30% , respectively, while the area with infected snails increased by 4.52%. The results of standard examination suggested that all the 15 uncontrolled counties ( cities, districts) reached the criteria of infection control. Conclusions Though the endemic situation of schistosomiasis in Hubei Province has been controlled effectively, the endemic condition is still severe. Therefore, the comprehensive measures with an emphasis on infectious source control should be strengthened to consolidate the control result.

Objective: To study the expression of PDCD5 mRNA and its significance in esophageal cancer in Xinjiang Kazakh and Han nationality. Methods: RT-PCR was used to detect the mRNA of PDCD5 in 40 cases of esophageal cancer (18 cases of Kazakh, 22 cases of Han). Results: The positive rate of PDCD5 mRNA expression in 40 samples of esopha-geal cancer tissue, adjacent tissue, and normal tissue was 80.0% (32/40), 80.0% (32/40) and 87.5% (35/40), respectively, with no significant difference (P>0.05). The Ods of cancer tissues, adjacent tissues, and normal tissues were 0.7644± 0.1444, 0.9341 ±0.1631 and 1.8703±0.4767, respectively. The expression of PDCD5 was significantly increased in cancer tissues compared with that in normal tissues (P<0.05). The expression level of PDCD5 mRNA was not significantly correlat-ed with the degree of differentiation and lymph node metastasis. Conclusion: No significant difference was found in PDCD5 mRNA expression in esophageal cancer between Xinjiang kazakh and Han nationality (P>0.05). The expression of PDCD5 is not correlated with the degree of differentiation, depth of invasion or lymph node metastasis. Detection of PDCD5 mRNA expression in esophageal cancer tissues may provide valuable information for patient prognosis.
